摘要
以苹果渣为原料,采取酸提醇沉法,研究酸类选择、脱色方法及不同类型果渣对制取高甲氧基果胶特性的影响。结果表明:不同酸液中以柠檬酸提取的产品得率最高;各种常规脱色方法对果胶脱色的效果不明显。以不同时期、不同干燥方法的苹果渣为原料提取果胶并进行检测分析发现,早期果渣较其它各时期的果渣所提取的高甲氧基果胶得率高,是提取高甲氧基果胶的较好原料。
With apple pomace as materials, with aqueous acid and precipitating with ethanol, acid selected, bleaching method,different kinds of apple pomace that dealing with the quality and quantity of the product were prepared. The results showed that the yield with citric acid was the highest among all the acids tested. Common decolorants was not effective to blanch the product. The early stage pomace gave both the productive and qualified pectin when different kinds of pomaces were employed.
